[PSUBS-MAILIST] Q-Sub

Hugh, WOW!!!
This sub is amazing, complex and the cockpit area is really cool. Have you
contracted with either agency to certify this unit, or are you building to
their specs and will certify prior to production models. Id be curious as
the cost they are estimating for your certification.

Best Regards,
